I don't know about it being a too small expansion per se, but I agree that the greater proportion of rares, epics and legendaries makes it more difficult to complete the GvG set. You see the same commons over and over again after just a few packs.

Do you need all legendaries though? Go for a staple like Dr. Boom and a couple of others that suit your favourite decks. If anything, fewer commons means more dust for crafting.

I'm not sure about websites but you might be interested in a book like this. It has a vocabulary list and explanatory notes at the end but I found it most helpful to just compare the translations line by line, starting with simple parts of the stories.

I greatly enjoy TB's casting most of the time but it felt a little forced this time around. It appeared as if the hype was intended to attract and excite first time viewers, but it has an unintended cost of frustrating and patronising regular viewers.

TB is clearly passionate about the game and so I hesitate to say that his hype could benefit from being tempered by a deeper understanding of the game--to know what actions really deserve hype and better predict the outcome of battles--because I don't think he intentionally creates false hype.

That said, the lineup was exceptional and I thank TB for making it happen.
